[patch] make ktrdump loop reading the ktr buffers

[Matthew Dillon]

:This patch adds a new flag to ktrdump(8) as discussed on kernel. -s 
:functionality has not been tested (no smp here). Cleans up the code a bit, 
:not as much as I would like, but still... Written during the week when I was 
:too sleepy to study so, please, *test* before commiting.

    Nice!  It does work.  I'm going to play with it a bit to see if I
    can make it work in sorted mode, and I'll try to fix the relative
    timestamp too.  Then I'll commit it.
